Human fatty acid binding protein‐4 (FABP‐4), a protein elevated in obesity that promotes colon cancer cell invasiveness and metastasis, may be associated with higher mortality in individuals with colorectal cancer (CRC) and may serve as a mediator of the obesity–mortality association in these individuals. We used a causal diagram to inform covariate selection and applied Cox proportional hazards models to estimate hazard ratios (HRs) for CRC‐specific, non‐CRC‐specific, and all‐cause mortality by FABP‐4 levels measured in baseline blood samples from 1371 incident CRC cases from the European Prospective Investigation into Cancer and Nutrition cohort. Competing risk analyses were adapted for CRC …

Faculty, Staff and Student Publications

Background: Late radiation-associated dysphagia (late-RAD) commonly presents in patients with signs of hypoglossal neuropathy, with hallmark clinical features including lingual atrophy, deviation, and fasciculation. Gold-standard electromyography (EMG) has not been used to explore the frequency of hypoglossal neuropathy in patients with late-RAD.

Methods: Exploratory post hoc secondary analysis of MANTLE trial (NCT03612531) was completed. The presence of cranial nerve XII (CN XII) neuropathy was classified by (1) features of clinical assessment as well as (2) intramuscular genioglossus EMG pre-MANTLE intervention in disease-free HNC survivors ≥ 2 years post-radiotherapy (RT) with grade ≥ 2 fibrosis and dysphagia.

Background: Proinflammatory cytokine production may be related to poor emotional adjustment in dementia spousal caregivers. People who display attachment insecurity may be at increased risk for adverse caregiving experiences and poor psychosocial outcomes.

Objective: This study aimed to understand whether proinflammatory cytokine production was associated with anticipatory grief, caregiver burden, and depressive symptoms and whether those relationships were stronger for caregivers higher on attachment anxiety or avoidance.

Method: A sample of 103 dementia spousal caregivers provided self-report data on demographics, health information, and psychosocial outcomes. We also determined lipopolysaccharide-induced whole-blood interleukin-6, interleukin-1β, tumor necrosis factor-α, and interleukin-10 production and combined …

A Comparative Study Of Statistical Methods For Identifying Differentially Expressed Genes In Spatial Transcriptomics, Yishan Wang, Chenxuan Zang, Ziyi Li, Charles C Guo, Dejian Lai, Peng Wei

Faculty, Staff and Student Publications

Spatial transcriptomics (ST) provides unprecedented insights into gene expression patterns while retaining spatial context, making it a valuable tool for understanding complex tissue architectures, such as those found in cancers. Seurat, by far the most popular tool for analyzing ST data, uses the Wilcoxon rank-sum test by default for differential expression analysis. However, as a nonparametric method that disregards spatial correlations, the Wilcoxon test can lead to inflated false positive rates and misleading findings. This limitation highlights the need for a more robust statistical approach that effectively incorporates spatial correlations. To this end, we propose a Generalized Estimating Equations (GEE) …

Melody: Mediation Analysis In Logistic Regression For High-Dimensional Mediators And A Binary Outcome, Sunyi Chi, Xingyu Li, Peng Wei, Xuelin Huang

Faculty, Staff and Student Publications

Mediation analysis is a pivotal tool for elucidating the indirect effect of an environmental factor or treatment on disease through potentially high‐dimensional omics data, such as gene expression profiles. However, traditional mediation analysis methods tailored for binary outcomes often rely on the rare disease assumption in logistic regression and provide inadequate measures of total mediation effect when multiple mediators have effects in different directions. In this paper, we develop a MEdiation analysis framework in LOgistic regression for high‐Dimensional mediators and a binarY outcome (MELODY). It leverages a second‐moment‐based measure analogous to the ��2 for linear models to quantify the total …

Faculty, Staff and Student Publications

Purpose: The FLASH effect occurs when radiation given at ultra-high dose rates spares healthy tissue while achieving isoeffective tumor control relative to conventional (CONV) dose rate irradiation. Limited data has implicated oxygen in the FLASH effect. This study investigated the effect of tissue oxygen tension (pO2) on gastrointestinal (GI) FLASH sparing in mice.

Methods: pO2 was quantified in vivo by electron paramagnetic resonance imaging (EPRI)- noninvasive oximetry through spin probe injection and magnetic resonance co-registration- and a phosphorescent quenching microsensor. B6(Cg)-Tyrc-2 J/J female mice were imaged while breathing 10%, 21%, and 95% oxygen. C57BL/6 mice of both sexes underwent microsensor …

BACKGROUND: The current understanding of the neural correlates of borderline personality disorder (BPD) is limited, but some evidence suggests that alterations in limbic structures play a role in adult BPD. The developmental course of structural neural differences in BPD is unknown. Whether there is specificity for structural alterations in BPD compared to other psychiatric presentations, such as major depressive disorder (MDD), remains unexplored. In the current study, we examined childhood trajectories of 2 limbic regions that have been implicated in BPD, hippocampal and amygdala volume, as they relate to adolescent BPD symptoms compared to MDD symptoms.

METHODS: Participants (n = …

2020-Current year OA Pubs

BACKGROUND: Excess adiposity is a major risk factor for insulin resistance, prediabetes, and Type 2 diabetes and increases the risk for sarcopenia and osteosarcopenia later in life. It has been proposed that altered metabolic function and musculoskeletal status in people with obesity are directly linked, presumably because they share common pathophysiological mechanisms. However, the effect of metabolic dysfunction, independent of adiposity, on musculoskeletal status is unknown.

METHODS: We performed a comprehensive assessment of musculoskeletal status in people with overweight/obesity and prediabetes (n = 12; 72% women; age: 67 ± 6 years; weight: 81 ± 11 kg; mean ± SD) and …

BACKGROUND: Protein EpiScores are a novel class of DNA methylation (DNAm)-based metrics proposed to measure peripheral immune system characteristics. Although Protein EpiScores have been associated with chronic disease risk, their relationship with colorectal cancer (CRC) survival has not been investigated.

METHODS: We generated new genome-wide DNAm data on pre-treatment whole blood samples from a case-control sample of 136 newly diagnosed CRC patients nested in the ColoCare Study and calculated 107 Protein EpiScores using the developer's algorithm. Over a median follow-up of 7.3 years (range: 0.3-13.8 years), 35 (26%) patients experienced disease recurrence, and 47 (35%) died. Protein EpiScore associations with …

Partial Versus Full Revision In Cementless Single-Stage Exchange For Hip Periprosthetic Joint Infection: A Multicenter Comparative Study With 10-Year Survivorship Analysis, Wenbo Mu, Atthakorn Jarusriwanna, Boyong Xu, Scot A. Brown, Xiaogang Zhang, Alexander Dawes, Javad Parvizi Md, Li Cao

Rothman Institute Papers

BACKGROUND: Periprosthetic joint infection (PJI) is one of the most challenging complications following total hip arthroplasty (THA). Traditional management typically involves full revision to ensure comprehensive infection eradication. However, for patients with well-fixed implants, partial revision in a single-stage cementless approach may provide a viable alternative, potentially preserving bone stock and reducing operative time. The relative efficacy of this approach compared with full revision remains to be fully explored. This multicenter study aims to determine whether partial revision in cementless single-stage exchange surgery offers comparable infection control outcomes to full revision for select patients with well-fixed implants.

METHODS: We conducted …

Expression Spectrum Of Te-Driven Transcripts In Human Adult Tissues, Benpeng Miao, Xinlong Luo, Amina Ademovic, Yushan Yang, Tao P Wu, Bo A Zhang

Faculty, Staff and Students Publications

Background

Transposable elements (TEs) are vital components of eukaryotic genomes and have played a critical role in genome evolution. Although most TEs are silenced in the mammalian genome, increasing evidence suggests that certain TEs are actively involved in gene regulation during early developmental stages. However, the extent to which human TEs drive gene transcription in adult tissues remains largely unexplored.

Results

In this study, we systematically analyze 17,329 human transcriptomes to investigate how TEs influence gene transcription across 47 adult tissues. Our findings reveal that TE-driven transcripts are broadly expressed in human tissues, contributing to both housekeeping functions and tissue-specific …

Janus kinases 1 and 2 and STAT transcription factors are critical signaling nodes for numerous growth factors. In the mammary gland, JAK2 and STAT5a/b are essential for alveolar cell differentiation and lactation, but little is known about the cooperative roles of JAKs and STATs before pregnancy. We examined female mice conditionally deficient in JAK1/2 and discovered that both kinases jointly regulate epithelial cell proliferation and ductal morphogenesis. To assess the role of downstream STATs, we generated genetic models co-deficient in STAT3/5a/5b with or without STAT1 or JAK1. Although loss of STAT3/5a/5b leads to a JAK1-dependent upregulation of STAT1, the formation …

Theoretical accounts typically assume that key features of human socio-cognitive development are universal. This paper reports a large-scale cross-cultural study (17 communities, diverse ethnicities, N = 1,377, 709 female, mean = 5.50 years, -collected March 2022 to January 2024) on gaze following in early childhood. To test for universality, cognitive processing signatures were derived from a computational model treating gaze following as social vector estimation. Results showed substantial variation between communities and individuals. Yet, the processing signature was found in all communities. Individual differences in performance were related to children's familiarity with the data-collection device but not opportunities for social …

SF3B1 is an essential and ubiquitous splicing factor that plays a pivotal role in the early steps of pre-mRNA splicing. Recurrent somatic missense mutations in SF3B1 are frequent in cancers, but no constitutional variant has been reported so far. We describe here a cohort of 26 individuals with neurodevelopmental disorders, harbouring SF3B1 constitutional heterozygous variants that appeared mostly de novo. Patients present with a global developmental delay, associated with variable neurological and facial dysmorphic traits. A dichotomy may emerge between patients harbouring predicted loss of function (n = 9) and missense variants (n = 17), the latter being associated with …

Multiple myeloma (MM) is consistently preceded by monoclonal gammopathy of undetermined significance (MGUS) and smoldering multiple myeloma (SMM). While these precursor conditions are asymptomatic, they are not entirely benign and carry a lifelong risk of progression to MM. Unlike other cancers defined by pathology, malignant transformation from MGUS or SMM to MM has so far relied on demonstration of clinical end-organ damage as morphology and cytogenetics cannot reliably distinguish them. In this study, using genomic data from 374 patients with MGUS or SMM (277 training, 97 validation), to our knowledge, we demonstrate for the first time the ability to identify …

Radionuclide-stimulated dynamic therapy (RaST) utilizes Cerenkov-radiating radiopharmaceuticals to activate light-sensitive drugs and materials, generating reactive oxygen species (ROS) that inhibit cancer progression. However, the underlying cell death mechanisms are not fully understood. Using ROS-regenerative nanophotosensitizers coated with a tumor-targeting transferrin-titanocene complex and radiolabeled 2-fluorodeoxyglucose, we found that RaST induced apoptosis and necroptosis, characterized by the activation of RIPK-1, RIPK-3, nuclear factor kappa B, and mixed lineage kinase domain-like pseudokinase, leading to membrane permeabilization, cytokine release, and the expression of immunogenic damage-associated molecular patterns. In immune-deficient breast tumor-bearing mice with adequate stroma and growth factors, RaST did not prevent tumor growth …
